This document (Adobe Acrobat format) outlines a legal ruing in the EU that seems to open the door for resale of digitally distributed software (thanks Joao). Here's a bit:

Where the copyright holder makes available to his customer a copy – tangible or intangible – and at the same time concludes, in return form payment of a fee, a licence agreement granting the customer the right to use that copy for an unlimited period, that rightholder sells the copy to the customer and thus exhausts his exclusive distribution right. Such a transaction involves a transfer of the right of ownership of the copy. Therefore, even if the licence agreement prohibits a further transfer, the rightholder can no longer oppose the resale of that copy.

Media is not a couch or a hammer. Media is media. Even an uneducated consumer should realize that different types of products require different types of laws.

I'll grant there are differences between buying a hammer and buying software. I can't make a copy of my hammer the way I can software. And I totally support laws saying I can't duplicate software and distribute it without permission. But to say software isn't mine, and that I can't sell it is silly. By your logic, anything that lasts long enough can't be purchased. Where is the line? How long is too long? Bookends -- I have bookends on my shelf that are as good as the day I bought them. Are they not mine? Can I not sell them?
